ASSIGNOB TO KELSEY-HAYES WHEEL A CORPORATION OF NEW YORK 'VEHICLE WHEELHUB AND BRAKE-DRUM ASSEMBLY Application led December 27, 1927'. SerialNo. 242,768.

The invention relates to vehicle wheels and refers more particularly tovehicle wheel hub and brake drum assemblies upon which demountable wheelbodies may be mounted.

invention is to balance the hub and brake drum assembly independently ofthe demountable wheel body, which latter is balanced, so that when thewheel body and rim assembly is mounted upon the hub and brake drumassembly the complete Wheel is balanced. Other objects of the inventionreside in the novel features of construction and combinations andarrangements of parts as more fully hereinafter set forth.

In the drawings Figure 1 is a front elevation, partly broken away, of avehicle wheel embodying my invention;

Figure 2 is a cross section on the line 2 2 of Figure l.

Figure 3 is a similar view of the vehicle wheel hub and brake drumassembly;

Figure 4 is a similar view of a modified vehicle wheel hub and brakedrum assembly.

The vehicle wheel is of that type in which the wheel hub and brake drumform a unit assembly and the wheel body is detachably mounted upon theassembly. As shown in the drawings, 1 is the wheel hub and 2 is thebrake drum, which is permanently secured to the hub and forms aunitassembly therewith. The hub has the fixed radially extending flange3 and the brake drum has the web 4, which latter is clamped against therear face of the fixed flange by means of the bolts 5 and nuts 6. Thebrake drum has the brake flange f 7 and the curled flange 8 at the rearedge of the brake flange for reinforcingr the latter and preventingchattering upon application of the brake. This reinforcing flange iscurled and extends outwardly and forwardly to form an annular recess 9.

The demountable wheel body inthe present instance is formed by the disk10, which is detachably secured to the hub and brake drum assembly bymeans of the bolts 1l and nuts 12. 13 is the tire carrying rim, which,in' the present instance, is of the solid base type and permanentlysecured to the periphto secure the same from accidental disthe curledreinforcing flange 8. As shown, Y

15 is such a weight which is preferably arcwelded to the reinforcingflange, this weight being of a size to counterbalance the hub and brakedrum assembly, which is separately shown in Figure 3. owever, it isapparent that if it is found desirable or necessary other weights may besecured in place to balance the assembly. By reason of this arrangement,the reinforcing flange assists in holding the weight or Weights inplace,- inasmuch as it has portions radially outward and inward from theweight or Weights. Furthermore, this reinforcing flange with the wheelbody conceals the weight or weights.

In the modification shown in Figure 4, the hub and brake drum assemblyis in general the same as that shown in the other views. However, thishub and brake drum assembly has the radially extending annular flange 16at the rear edge of and reinforcin .the brake flange 17 of the brakedrum and for balancing thepassembly the rear face of this reinorcingHarige has sufficient metal removed therefrom at one or more points 18to place the assembly in balance, there being suflicient metal left inthe reinforcing flange to make the latter sufficiently rigid and strongto carry out its functions.

What I claim as my invention is:

1. In a vehicle wheel hub and brake drum assembly, the combination of ahub and a brake drum secured to said hub and having a brake flange and aflange for reinforcing said brake'flange constructed-to balance theassembly.

2. In a vehicle wheel hub and brake drum assembly, the combination of ahub, a brake drum secured to said hub and having a brake flange and aflange for reinforcin said brake iange, and means for balancing t eassembly,

including a weight secured to said reinforcing iange.

3. In a vehicle wheel hub and brake drum assembly, the combination of ahub, a, brake drum secured to said hub and having a brake ange and asecond flange reinforcing said brake flange and forming therewitharecess, and means for balancing the assembly, includingv a weight in therecess and secured to said reinforcing ilange.

4. In a vehicle wheel hub and brake drum assembly, the combination of ahub, a brake drum secured to said hub and having a brake flange and acurled ange for reinforcing said brake flange forming an annular recess,and means for balancing the assembly, inl,

cluding a weight located in the recess and Secured to said reinforcingange.

5. In a vehicle wheelliub and brake drum assembly, the combination of ahub, a brake drum' secured to said hub and having a brake iiangeprovided at its edge with a curled reinforcing ange, and balancing meanssecured within said reinforcing iiange andconcealed thereby.

6. In a vehicle wheel, a. brake drum having a brake flange, and a flangefor reinforcing said brake flange constructed to balance the brake drum.

7. In a vehicle wheel, a brake drum assembly including a brake flange, afiange for reinforcing said brake flange, and means for balancing theassembly including a weight secured to said reinforcing iange.

8. In a vehicle wheel, a brake drum assembly including a brake flangeterminating in. a curled reinforcing flange cooperating with sald brakefla-nge to form a recess, and

means for balancing said assembly including a Weightsecured within therecess aforesaid. In testlmony whereof I aix m si nature.
